1.725MW 10kV Medium-Voltage Hybrid Solar Energy Storage Power Conversion System with Transformer Isolation
1.725MW 10kV Hybrid Solar Energy Storage Power Conversion System
The Voltertech BESS-1725MW-W is a 1.725MW transformer-isolated power conversion unit designed for MW-scale hybrid solar and battery energy storage projects. It connects a compatible 1000–1500V DC battery system to a 10kV medium-voltage AC network and supports project-level EMS and dispatch communication.
1.725MW PCS for Hybrid Solar + Battery Projects
In a large hybrid solar plant, PV generation, battery storage and the grid must operate as one coordinated energy system. The BESS-1725MW-W provides the power conversion interface for the battery side, allowing stored DC energy to be converted for a 10kV AC network.
Its 1.725MW power class makes it suitable for solar-plus-storage plants, industrial microgrids and other MW-scale renewable energy projects.

Matching the PCS with Battery Storage
The 1.725MW rating describes the power conversion capability of the system, while battery capacity is specified separately in MWh. The required battery capacity therefore depends on the target discharge duration and operating strategy.
During project design, the battery voltage must also remain compatible with the specified 1000–1500V DC operating window.
- Confirm required PCS power in MW
- Define target battery discharge duration
- Calculate the required battery MWh capacity
- Check battery DC voltage against the 1000–1500V range
- Confirm site and grid connection requirements
10kV Medium-Voltage Solar BESS Integration
The AC side is rated at 1725kVA and 10kV, allowing the unit to connect the battery conversion section to a medium-voltage project network.
Transformer isolation is integrated into the AC-side architecture, while an adjustable power factor from -1 to +1 provides additional flexibility when matching the PCS to project electrical requirements.
EMS and Plant Dispatch Control
Hybrid solar projects require coordinated control between battery storage, PCS, PV generation and grid operation. The BESS-1725MW-W provides communication interfaces for both battery-side control and plant-level dispatch.
- CAN / RS485 for battery communication
- Modbus RTU for compatible control equipment
- Modbus TCP for network communication
- IEC 60870-5-104 for compatible dispatch systems
Final EMS and SCADA compatibility should be checked during project engineering.
Typical Applications
MW-scale battery conversion for photovoltaic and energy storage projects.
10kV battery power conversion for hybrid generation and industrial loads.
High-voltage battery integration for large renewable power systems.
Transformer-isolated PCS interface between battery storage and a 10kV network.
Frequently Asked Questions
1. How is a 1.725MW PCS used in a hybrid solar system?
The PCS converts energy between a compatible high-voltage DC battery system and the AC network. In a hybrid solar project, it works with the battery, EMS and other plant equipment to manage battery charging and discharging.
2. How much battery capacity is needed for a 1.725MW PCS?
Battery capacity depends on the required discharge duration. The 1.725MW rating defines power, while the battery energy requirement should be calculated separately in MWh according to the project's operating hours and usable energy target.
3. What battery voltage can be connected?
The specified DC operating range is 1000–1500V with a maximum DC current of 1808A. The battery configuration should be engineered to remain within these electrical limits.
4. Can this PCS connect to a 10kV solar plant network?
The AC side is rated at 1725kVA and 10kV with transformer isolation. Final connection, protection and grid-compliance requirements should be confirmed according to the project's electrical design.
5. Can it communicate with a project EMS or SCADA system?
Yes. Dispatch communication options include Modbus RTU, Modbus TCP and IEC 60870-5-104, while CAN and RS485 are provided for battery communication. Final protocol compatibility should be confirmed before project integration.
6. What should I provide when requesting a 1.725MW hybrid solar solution?
Provide the PV capacity, required PCS power, target battery MWh and discharge duration, battery DC voltage, grid voltage, communication protocol, site temperature, altitude and project location.
